Satisfying simple logic level, enlivened by great looking gear mechanism and some intricate gameplay for B between bottom of stairs and the gear wheel
Very nice level but ... Spoiler that push move at the bottom is very hard to perform without ending up on the wall. Love the cog though - thanks.
@gmacpro Spoiler 1) Standing like this you can easily push B to the left. This spot is easy to reach due to the low ceiling trick. But I guess you mean the other push. 2) Having pushed B to the left, move him to this position, again easy with low ceiling. 3) Straighten out the cog, not very fast, and B should end up in this position. For the other side on the way back the same thing. On both sides in the other direction you can simply reverse the steps.
Nothing difficult but what a great and smooth mechanism! I love seeing such things and you've built it perfectly.
Wow, what a fantastic mechanism, I am impressed and enthusiastic...have I already said "wow"? ;0) THANKS!!!
